Insert Witty Journal Title Here

I'm an INTP. My wife is an ESTJ, which leads to interesting differences in perspective at home. I totally understand the problem with with the "what if?" scenario. I can spend weeks, running down rabbit holes to make sure that everything is logical and plausible and consistent, only to prove to myself that it would never happen in the "real world". I don't usually require quite so much plausibility in the SF that I read, so somewhere I have to figure out where that line is, where I can say "assume for the purposes of this story that the following is true." But handwaveum has to come in pretty small doses to be tolerable. It's also a little easier to do it with fantasy than it is with SF, because the changes from reality don't have to be plausible, just consistent.
